Doc#8004 WHY DOES LOW-E WORK? It’s the Law! The second Law of Thermodynamics, unlike man made laws, cannot be broken HEAT goes to COLD by: CONDUCTION CONVECTION, OR RADIATION (INFRARED) WHAT IS CONDUCTION? When two surfaces come in contact, the warmer surface gives up heat to the cooler surface as can be seen with a glowing burner on a stove heating the pot it is in contact with. In a building this is limited primarily to studs connecting outer and inner surfaces WHAT IS CONVECTION? The movement of air as a result of air being warmed. Warm air rises seeking the coldest point. Convection is visible as wavy lines above a hot road. Convection is a major concern in the winter, but not in the summer. WHAT IS INFRARED RADIATION? Electromagnetic waves that can only be seen as part of the rainbow. It travels at 186,000 miles a second. Radiant energy travels in all directions seeking a cooler object to strike and then generates heat. Microwave ovens work on the same principles. Standard ovens heat the air, while a microwave heats what it sees.. Infrared is like microwaves at lower frequencies. Most of us do not understand microwaves or electricity but we use and enjoy the benefits of them. We may not understand infrared radiation but we can learn to make it work for us by learning how to control it. Doc#8004.2 2 WHY DO WE INSULATE? 1) For Comfort 2) To reduce Energy Consumption 3) To help Control Condensation What is an R-Value? R-Value is the resistance to CONDUCTIVE heat flow. Conduction is only 3-7% of total heat loss. Mass Insulations only deal effectively with conduction. Does R-Value have any effect on Infrared heat? No, Most mass type insulations absorb Infrared like a sponge and store it like a battery allowing it to escape where we don’t want it. Does R-Value have any effect on convective heat loss? Some. With recent studies by Oak Ridge National Laboratories they have found the colder your attic gets the more heat loss you have through convective currents. R-Values were found to be reduced by as much as 50% in the winter. What about Moisture? Most mass insulations absorbs moisture, especially in the winter when warm moist convective currents find a cold surface. Once this occurs, the R-Values drop tremendously and in extreme cases the insulation must be removed. Doc#8004.3 3 Lets Take A Look Heat Loss through Walls Heat Loss through Ceiling/Roof Summer Heat Gain Convection Conduction Radiation 100% 0% 0% 90% 10% 3% to 7% Up 15% to 20% 80% 20% to 70% 30% 93% 3% 60% 40% to 7% 50% 50% Conduction 40% 60% 30% 70% Up 50% 65% to 85% 20% 80% Radiation Convection to to 3% to 7% 10% 45% 75% 90% 0% 100% Convection Conduction Radiation 0% 10% 20% 30% 40% 50% 60% 70% 80% 90% 100% Now that we understand the three forms of heat loss and gain, the question is, “Is R-Value the only insulating option that we should think about?” When insulating we must take into consideration all three forms of heat loss and gain. Like millions of Americans you have done a great job solving conductive heat loss. What are you going to do about the other two? Especially Infrared! Doc#8004.4 4 Is Infrared Blocking A New Form Of Insulating? Infrared blocking, also known as reflective insulation and radiant barrier is one of the oldest forms of man made insulation. Dating back to the late 1700’s, the first recorded form is the DeWars flask, which we know today as the glass lined Thermos bottle. Lets face it, there has never been anything better for keeping something hot in the winter, or cold in the summer than the Thermos bottle. During World War II, the government confiscated aluminum shutting down the reflective insulation industry, thus ushering in the mass insulation industry, with asbestos, fiberglass and cellulose. All three are relatively new forms of insulation. It wasn’t until the 1960’s, with the advent of the space program, that NASA brought back infrared blocking in astronauts suits, spacecraft insulation and just about anything they send into space. So many things in our everyday life are a result of space technology, like calculators and computers, isn’t it time to benefit from Infrared Blocking! Turn your By using building Low-E as into a an Thermos Infrared bottle. Blocker In our everyday life we use Low-E benefits. When we bake a potato, we wrap it in aluminum. When we roast the Thanksgiving turkey, we cover the legs and back to keep it from scorching. Many food items are sealed in aluminum to keep them fresh. For years, windows were the big problem in our homes when dealing with heat loss and gain, then they coated windows with a low-e coating, making them more efficient. Isn’t it time we make our walls and ceilings as efficient? Doc#8004.5 5 What does Low-E mean? Understanding what Low-E means can be difficult. All surfaces have an “e” rating from .01 to 1.0. The “e” stands for emissivity, which is the ability of a surface to reradiate or give off radiant heat to a cooler surface. The lower the “e” rating, the lower the amount of radiant heat the surface will give off. For example, a wood stove surface has an “e” rating of 1.0, meaning that at 10000 it will give off 100 in infrared. Cover it with a Low-E surface with an “e” rating of .03 then that surface will re-radiate only 30 in infrared! All building products have an “e” rating, most of them over .80 The graph below demonstrates what Low-E surfaces can do for you What can Low-E do for me?

Why is a Low-E surface highly recommended? The left sides of the houses above are demonstrating the potential heat loss and gain in buildings using only mass type insulations. The right sides of the house demonstrate the potential reduction in heat loss and gain by adding Low-E with the mass insulations. Which would you rather be heating and cooling? Doc#8004.6 6 Comfort If it wouldn’t be for comfort, we wouldn’t have much of an energy bill, would we! In the winter we would keep our buildings just above freezing , and in the summer HOT. Have you ever been in a room in the winter and you felt chilly, but when you looked at the thermostat it said warm? We’ve always been told “turn on the humidifier and turn up the heat.” Chances are you were losing your body heat through infrared radiation especially if you were near a block wall or a window. What do the police use to look for criminals at night? What does the utility company use to check for heat loss? An infrared gun or infrared camera. Environmental Standards “Less appreciated is the fact that when walls are cold, the occupant can lose so much heat by radiation that he is cold, complains of drafts (which may or may not be present), and uncomfortable even with a relatively high air temperature. This loss of heat by radiation is especially noticeable if a person is sitting next to a window when the glass is cold. At the same time another occupant who is not losing heat by radiation may feel quite comfortable. Such situations cause great irritation among occupants of homes and offices. Since there is no universally acceptable standards in regards to mean radiant temperature, relative humidity, and air motion, air temperature is, in actual practice, the primary basis for design.“ Encyclopedia Britannica 1971 Have you ever been sitting at home in the summer, in the evening, air conditioner running like crazy and you’re HOT! And you feel like you’re sitting in your microwave and its on HIGH! That sneaky INFRARED found its way down through your ceiling.
